Summary: In this study, the binding ability of high-strength graphene to Al, Cu, Zn, Li, and Mg atoms was analyzed by first-principle calculations. The adsorption of metal atoms causes lattice distortion and Al, Cu, and Li atoms show good adsorption potential on graphene. The explicit electronic interaction between metal atoms and carbon atoms results in different adsorption energies. The mechanical properties of the interface structure between (111) crystal plane and graphene were also studied.

Summary: Montmorillonite (Mt) is a significant material for wastewater treatment due to its good adsorption capabilities for organic pollutants and heavy metal ions. However, its difficulty in separating from water limits its application. In this study, polyvinylformal-Mt (PVFM-Mt) composite particles were prepared to overcome this issue. PVFM-Mt exhibited excellent separation performance and higher removal rates compared to Mt, providing a theoretical and practical foundation for the extensive application of clay mineral materials in wastewater treatment and large-scale production.

Summary: The SDS/CTAB@Mt composite, prepared through the synergistic effect of CTAB and SDS, showed a highly negatively charged surface and good adsorption properties for malachite green. The adsorption process followed the Langmuir model and pseudo-second-order kinetics, with a maximum adsorbed amount of 1021.45 mg/g. Thermodynamic parameters indicated that the adsorption of malachite green onto the composite was spontaneous, exothermic, and led to a decrease in randomness of adsorbed molecules.

Summary: In this study, chitosan/montmorillonite composites were synthesized by modifying the montmorillonite mineral with chitosan, and their usage as adsorbents for removing Remazol Brillant Blue R and Malachite Green dyestuffs from aqueous solutions was investigated. The characteristics of the synthesized composite were determined using SEM, FT-IR, XRD, and BET analysis techniques. The effects of different batch parameters on the adsorption process were examined. The results showed that CCS/MTs are suitable adsorbents for RBBR and MG removal from aqueous solutions due to their high adsorption capacity.

Summary: The study investigated the removal and oxidation of seven perfluorinated compounds using an iron-clay-cyclodextrin polymer composite. The composite showed excellent adsorption and efficient oxidation, especially towards high molecular weight compounds. It also exhibited stable degradation activity even after multiple cycles. These findings suggest that composites promoting surface confinement of pollutants can be used for efficient removal and destruction of highly recalcitrant pollutants.

Summary: The study focused on the thermal insertion of ceria into montmorillonite clay to efficiently remove Cr (VI) oxyanions from aqueous solutions. The synthesized CeO2/Mt composite showed a high adsorption capacity and stability for the removal of Cr (VI), with a 100% removal efficiency achieved within 90 minutes at low initial concentrations and pH values. This composite material holds promise as an effective adsorbent for water contaminated with Cr (VI) oxoanions.

Summary: The size and shape of nanoparticles, such as graphene oxide (GO) platelets, have a significant impact on the properties of nanocomposites, including their mechanical strength and antibacterial effects. The current study demonstrates that increasing GO sheets in gelatin hydrogels improves mechanical strength and bactericidal capacity, particularly against drug-resistant strains. Therefore, the lateral dimensions of GO sheets play a crucial role in determining the properties of hydrogels.
